Una espuma (semi)rígida de celda abierta de poliuretano y poliisocianurato modificado con uretano que esobtenible por el método. Un panel de aislacion evacuado que comprende un material de relleno el cual consiste de la espuma (semi)rígida de celda abierta depoliuretano o poliisocianurato modificado con uretano. Una composicion de poliisocianato que es utilizable en el método.Method for the preparation of a (semi) rigid open cell foam of polyurethane or urethane modified polyisocyanurate by reacting a polyisocyanate composition with a polyfunctional composition reactive with isocyanate under foaming conditions, in which the composition has a free NCO value from 21 to 30% by weight and comprises the reaction product of a stoichiometric excess of an organic polyisocyanate and an isocyanate reactive material comprising a polyether polyol having a number between 1000 and 10,000 and an average hydroxyl nominal functionality of 2 to 6 and It contains 10 to 50% by weight of oxyethylene units. A (semi) rigid open-cell polyurethane and urethane-modified polyisocyanurate foam that is obtainable by the method. An evacuated insulation panel comprising a filler material which consists of the (semi) rigid open cell foam depolyurethane or urethane modified polyisocyanurate. A polyisocyanate composition that is usable in the method.
